You can try this:

szap -a 0 -c channels_astra.conf -r "TV3 CAT"
cat /dev/dvb/adapter0/dvr0 > testvideo.mpg
mplayer testvideo.mpg

This is for DVB-S, you can change it with tzap, first you need to scan
your local channels.

I tried that, but cat tells me that the device is busy:

root@werecit1:/opt/utils/tv# tzap -c /etc/channels.conf -r "Rai 1"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/etc/channels.conf'
tuning to 177500000 Hz
video pid 0x0200, audio pid 0x028a
status 00 | signal 1b1b | snr 000c | ber 0000ffff | unc 00000000 |
status 1f | signal fefe | snr 00f6 | ber 000000bd | unc 00000282 | FE_HAS_LOCK
[last line repeated several times]

In another console:

root@werecit1:~# cat /dev/dvb/adapter0/dvr0 > prova.mpg
cat: /dev/dvb/adapter0/dvr0: Dispositivo o risorsa occupata

Could you help me please?

You can use gnometv for that. It is also part of dvb-utils package.

Sorry... the name of the application is: gnutv

You'll use it with something like:
	$ gnutv -out file test.mpeg -channels channel.conf mychannel

PS.: I'm fighting with a gnome application here that is doing something bad
when called fom xfce... so, "gnome" come to my mind, instead of "gnu" ;)

Thank you very very much!!!
It works!! :-)

Re: Record DVB-T from command line

[shacky]

One question.
What if I need to record two channels in the same multiplex in the same time?
Gnutv does not let me it, because the second recording command returns
me that the device is busy, but I know this is possible (I know a
Windows program - TV Scheduler Pro - that make it.

Could you help me please?

Thank you very much!
Bye.
